Test elevation map + control on Go2

[ylenianistico]

This will be done feeding the elevation map with the pose estimated by

• DLIO (in this case we will use the LiDAR point cloud)
• or RGB-D-inertial ORB-SLAM3 (in this case we will use the camera point cloud). A Realsense D435i has been mounted on the Go2, using the support provided by Unitree
